Mott v Philip; Prosser v Philip

In the case of Mott v Philip and Prosser v Philip, the plaintiffs, Mott and Prosser, sought damages for injuries sustained in a road accident occurring immediately north of a section of roadworks. The defendants were Philip, the driver of the oncoming vehicle, and several companies responsible for the roadworks. The plaintiffs alleged negligence on the part of both Philip and the roadworks defendants. The case was heard in the Supreme Court of New South Wales.

The primary legal issues revolved around determining whether Philip was negligent in his driving and whether the roadworks defendants were negligent in managing the roadworks. Specifically, the court had to consider whether the loose aggregate on the road surface caused the loss of control of Philip’s vehicle and if the roadworks should have been managed in a way that allowed for safe traversal. Additionally, the court had to evaluate whether the absence of a compulsory 60 kph speed limit sign contributed to the accident.

The court found that the roadworks defendants were negligent in not ensuring the road was safe for traversal, particularly due to the presence of loose aggregate. While Philip was not found to be negligent for adhering to the advisory speed sign, the court held that the absence of a compulsory 60 kph speed limit sign contributed to the accident. The court concluded that had such a sign been present, it might have prompted Philip to slow down sufficiently to maintain control over his vehicle. Therefore, the roadworks defendants were held liable for the accident, while Philip was not found to be negligent.

The court ordered judgment for each plaintiff against the second defendant in each proceeding. The claims against the third and fourth defendants (in 54/15) and the third, fourth, and fifth defendants (in 53/15), by each of the plaintiffs and by the first and second defendants, were dismissed.
